This page lists some fun software for visualization of geometry in 2D.
Hyperbolic Tesselations Applet is a Java applet that draws hyperbolic tilings. Superb! By Don Hatch. Home page: http://www.plunk.org/~hatch/HyperbolicApplet/ Java
MagicTile by Roice Nelson. This program lets you play Rubik's cube represented thru a Stereographic Projection. It also has lots of other Magic Polyhedron variations, all steographically projected. Too bad is that the software show only the projected 2D image only, not the actual 3D projection scene. Home page: http://www.gravitation3d.com/magictile/. Win
MoebApplet, by Paul Murray. This Java applet does real-time interactive Mobius transformation. If you are studying Mobius Transformation, this is the best applet for it. You can drag the fixed points, the poles, and a few other critical points in the plane and see the image change as you move.
NonEuclid by Joel Castellanos. It is a free software for drawing hyperbolic geometry. Its function is similar to Geometer's Sketchpad except it is not real-time interactive. Elements cannot be dragged around once drawn. The program comes with a tutorial on hyperbolic geometry. Home page: http://cs.unm.edu/~joel/NonEuclid/NonEuclid.html. Java
Space Jewels is a Java game, where you drive a spaceship in hyperbolic space to collect jewels. Author is Matthew Cook (b1970).
